Abstract (en)
[origin: WO2011153330A1] Electrochemical capacitors and methods for producing such electrochemical capacitors. The electrochemical capacitor can have an initial charged state and a cycled charged state and can include an anode, a cathode, and an electrolyte. The anode can include a first mixture having a first plurality of electrically conductive carbon-comprising particles having a first average porosity. The cathode can include a second mixture having a second plurality of electrically conductive carbon-comprising particles having a second average porosity greater than said first average porosity. The electrolyte can be physically and electrically contacting said anode and said cathode, and the first mixture in the cycled charged state can be substantially free of lithium metal particles and can further include a plurality of lithium ions intercalating the first plurality of carbon comprising particles. The mass ratio of the cathode and the electrolyte can be less than 1.
